CLAIR D. LAKE, OF BINGHAMTON, AND GEORGE F. DALY, OF JOHNSON CITY, NEW YORK, ASSIGNORS- TO THE TAIBULATING MACHINE COMPANY, OF E'NDICOTT, NEW

YORK, A CORPORATION OF NEW JERSEY cAan REPRODUCING MACHINE Application filed October 27, 1930. Serial No. 491,384.

The present invention is directed to improvements in card punching apparatus.

In the tabulating machine art it is the common practice to punch cards with perforations which designate various kinds of statistical data. These cards are then utilized in sorting and tabulating machines to obtain various classified records of the data on the cards. In the use of such systems it becomes necessary from timeto time to duplicate comparatively large groups of cards.

The cards themselves have been improved as regards the configuration of the perforations employed and the spacing between adja- Cent columns has been reduced to permit a greater amount of information to be punched in -a single card. It has therefore become desirable to transfer the information contained on the old type of card to the new so that the data may be sorted and tabulated on machines designed to operate. under control of the new type of card.

Such duplications if performed by hand punching would be time consuming, expensive and difiicult. Furthermore, copied cards which depend upon the operators reading the previously punched card are subject to errors.

In making such duplicated cards it is sometimes desirable to suppress a part of the data derived from the original punched card and in other cases it is desirable to arrange the punched data on the new cards in different fields and columns than that of the original cards.

It is further desirable to .provide for automatically effecting punching of certain repetition data on the new cards and for disposing such repetition data in any desired fields or columns thereof.

The present invention is directed to the provision of a punching machine and aremote, independent sensing machine, in which groups of blank and punched cards may be placed respectively, and which when in operation automatically feed blank and punched cards step by step therethrough, the sensing machine reading the punchings of the punched cards and effecting a corresponding punching of the blank cards.

Provision is made for permitting the suppression of punching of desired data derived from the punched cards and provision is also made for permitting the transposlng of data derived from a given field or column upon the punched cards to other fields or columns upon the blank cards.

Another object is to provide a card reproducing system in which a punching machine is remotely controlled by a card sensing machine and inwhich both machines have sep-- vided so that feeding of a punched card to position is accompanied by a correspondingfeeding of a blank card 'and in which feeding of one is suppressed until sensing or punching operations upon the other have been concluded.

Another object is to provide a card reproducing system having a punching machine in which blank cards may be hand punched wholly or in part.

' Various other objects and advantages of my invention will be obvious from the following particular description of one form of mechanlsm embodylng the invention or from an inspection of the accompanying drawing;

and the invention also constitutes certain new,

and novel features ofconstruction and combination of parts hereinafter set forth and claimed.

Oard feeding mechanism The card feeding mechanism is the same for both the sensing and punching machines and it will be understood in the following description of the. operation of the punching machine feeding mechanism that similar parts in the sensing machine perform similar unctions.

Cards are fed from supply hoppers 10 and 10a (Fig. 1) by picker knives 11 and 11a. which advance the cards to present their first columns to punching and sensing positions respectively. In this position card carriages comprising pusher-s 12 and 12a and forward guides 13 and 13a (Figs. 3 and 10) engage the cards and advance them step by step under control of escapement mechanism to be described later.

Pusher 12 and guide 13 are carried by an escapement rack 14 andpicker knife 11 is carried by a rack bar 15 (see also Fig. 2). Rack 14 has a gear 16 meshing with its loweredge and bar 15 has a gear 17 meshing with its upper edge, both gears being mounted upon a cross shaft 18. Due to this connection between the elements, movement of picker 11 toward the left as viewed in Fig. 1 is accompanied by movement to the right of pusher 12 and this action will deliver a card from the bottom of hopper 10 to punching position where pusher 12 engages it and further advance will be under control of the escapement mechanism. A one-way clutch mechanism generally designated at 19 in Fig. 2 permits the immediate return to the left of bar 15 and picker 11. Escapement rack 14a of the sensing machine is similarly geared to bar 1501 and related parts are similarly numbered with the letter a sufiixed.

The operation of card feeding just outlined is more fully explained in Patent No. 1,772,186 to F. L. Lee, et al, for a Duplicating punching machine and needs on further description here. The escapement mechanism referred to is of the same general nature as that disclosed in the Schaafl' Patent No. 1,426,223 and a brief description thereof will be given later.

Secured to the underside of the base of each machine is a motor 20 (Figs. 2 and 3) coupled to a stub-shaft 21 to which .is secured a worm 22 in mesh with a worm wheel 23 secured to a shaft 24 one end of which has secured thereto a ratchet shaped clutch element 25. Loosely mounted on shaft 24 is a gear 26 meshing with teeth on the lower edge of rack bar 15 and on which gear is mounted a disk 27 Pivoted at 28 to disk 27 is an arm 29 having a clutch tooth 30. The free end of arm 29 is connected to a toggle plate 31 by a link 32, the end of toggle plate 31 distant from its pivot 33 being articulated at 34 to a rod 35. The rod 35 is spring impelled and fits in an aperture in a pin 36 rotatably mounted on disk 27.

For the purpose of effecting a clutching action a magnet 37 is provided and when energized attracts an armature 38 so that arm 39 engaging a pin 40 of arm 29. will rock the tooth 30 into engagement with ratchet wheel 25. Through link 32 the toggle connection will be moved centrifugally, the spring on rod 35 acting to hold clutch tooth 30 in engagement with the ratchet teeth. Gear 26 will thereupon be driven in a counterclockwise direction substantially a single revolution shifting rack bar 15 to the left tofeed a card from the supply hopper. This will result as premised before in the movement of pusher 12 to the right to engage the newly fed card.

At the termination of the counterclockwise movement of gear 26, a tail 41 of arm 29 will strike a projection 42 of a fixed plate to effect the disengagement of the tooth 30 and ratchet 25'by a reverse action. Gear 26 and rack bar 15 are returned to the position of Fig. 2 through a gear 43 connected to a spring barrel (not shown). The one-way clutch 19 permits such action without affecting the escapement rack 14.

Also secured to the pivot of armature 38 is an arm 44 (Fig. 3) the free end of which is adapted to bear upon an insulating block to open contacts 45 and close contacts 46 when magnet 37 is energized. The contacts are maintained in shifted position by a latching bell crank 47, a lug of which is adapted to be engaged by a bent up plate 48 secured to gear 26, at the termination of the driving movement of the latter.

Automatic card ejector Means are provided in both machines for automatically removing completely sensed and punched cards and depositing the same in receptacles provided for the purpose. This invention is described in detail in the application of J. M. Cunningham, Serial No.

. ergized.

390,755, filed September 6, 1919 to which application recourse may be had for details of construction and operation.

Stated generally the gripper (Fig. 8) comprises a pair of jaws and 51 urged together by a flat spring 52 but the abutment of a pin 53 with the upper jaw 50 separates the jaws in order that the punched card (or sensed card) may be'received by the slit-like separation. The card occupies a position between the jaws at the termination of the punching or sensing of the last columns of the card.

, The gripper is pivotally mounted on a shaft 54 to which is secured a gear 55 adapted to be driven by a gear 56 through an idler gear. Meshingwith gear 56 is a slidably mounted rack 57 the extremity of which terminates in an adjustable cylindrical plunger 58. During the previous restoration of the card carriage the end of rack 15 (Fig. 9) engaged plunger 58 to shift rack 57 to the left against the tension of a spring 59. This caused a clockwise movement of shaft 54 through the train of gears 56--55 to bring the gripper unit to the position shown in Fig. 8 whereupon a latch lever 60 engaged a shoulder 61 of the lower jaw 51. Incidentally a certain amount of compression was stored up in spring 59. Shifting of latch 60 is effected by energization of the magnet 62 which attracts its armature 63 when the magnet is en- This causes a shifting movement of a link 64 to the right and by means of a cam shoulder 65 and arm 66 secured to the pivot shaft of latch 60 will rock the latter.

This will result in the release of spring 59 to cause the counterclockwise rotation of the gripper unit. As the jaw 50 leaves pin 53 spring 52 will act to close upon the lower jaw 51 thussecurely gripping the card and flipping the same in reversed position. A stationary pin 67 may suitably coact with one of the jaws to separate them permitting the released card to fall into a receptacle 68. As the card is ejected shifting of rack 57 by spring 59 will cause a square shoulder 69 (Fig. 9) to engage and close a contact 70 and in the sensing machine contact 7 0a..

Gard sensing mechanism Referring to Fig. 10 the perforated card is in position between guide 13a and pusher 12a and is adapted to move step by step past a series of sensing brushes 71 of which there are thirteen adapted to bear againt an insulated conducting bar 72. The brushes 71 are carried by an insulating brush holder 73 secured between a pair of side plates of a yoke or bail shaped member 74. Each side plate is suspended at its upper end by a link 75 pivoted to the frame portion 76 and at theirlower ends the side plates are supported by means of parallel links 77. plate of bail 74 and related link 77 is a toggle plate linkage member 78 which-is pivoted upon a rod 79. The ends of links 77 distant from their connecting points to the toggle plate 78 are pivotally secured to a pivoted armature structure 80. The armature 80 is attracted against the tension of its spring when magnet 81 is energized at which time the counterclockwise rocking of toggle plate 78 will be effective to elevate frame 74 resulting in the contact of the individual sensing brushes 71 with the common bar 72. Rocking of armature 80 also causes opening of a pair of contacts 82. Brushes 71 are adapted for continuous sliding contact with associated springs 83 which are wired to the punch selecting mechanism of the punching machine. Thus the brushes 71 are out of engagement with bar 72 except at such times as magnet 81 is energized. Twelve of the brushes make contact with the bar through perforations in the card and the other is located beyond the lateral edge of the card and serves to supply current to the bar when raised.

Sensing machine escapement In a manner to be explained in connection with the wiring diagram magnet 84 is energized to operate the step by step escapement of the sensing machine card carriage. Upon energization of magnet 84, its armature 85 will be rocked about its pivot in a clockwise direction and through a screw stud in an arm 86 secured to rod 87 will rock the rod counterclockwise against the tension of a spring 88. Rod 87 is rocked as an incident to each spacing operation and has secured at one end oppositely extending arms 89 and 90 (see also Fig. 10a) of which .89 is provided with a laterally extending pin 89a for engagement with an enlarged opening in a stepping dog 91 which is loosely pivoted on rod 87. The opposite arm 90 is provided with a pin 90a extending in a slot formed in the locking dog 92 between its pivot and its engaging end. When rod 87 is rocked, arm 89 will, through pin 89a, lift the stepping dog 91 out of one of the notches in the rack 14a and at the same time arm 90 will depress locking dog 92 into a notch'between the rack teeth. At this time a spring 93 advances the loosely pivoted dog 91 a short distance but suflicient to permit this dog to move Intermediate each side Lil Punching machine escapemcnt The escapement mechanism of the punching machine (Fig. 6) is similar to that just described, comprising a stepping dog 94, a locking dog and an operating arm 96 mounted on a rod 97 The rod 97 is rocked to escape rack 14 one tooth as an incident to a punching operation in a manner presently to be described.

Operation of the punching machine In Fig. 3 the punches 100 are of rectangular cross-section and mounted in a manner disclosed in the Patent 1,7 7 2,186, issued to F. L. Lee et al., dated August 5, 1930, and are normally held in raised position by springs 101. Resting on the upper ends of said punches are interposers 102 supported at their rear ends on a cross member 103. The interposer-s 102 are so notched at their forward ends that when they are in normal position as shown depression of an actuating plate 104 against a spring 105 will move a portion 106 of the plate into such notches.

However, when any numeral magnet 107 is energized under control of the sensing brushes 71 it will actuate its armature 108 to depress the corresponding key 109 which in turn will actuate a bell crank 110 against the action of a suitably connected spring. The upright arm of each. bell crank 110 has a pin and slot connection with an interposer 102. Such interposer will then be advanced to such a position that depression of the member 104 will effect depression of the interposer and consequently of the corresponding punch.

Upon movement of any of the interposers 102 a pair of contacts 111 are adapted to be closed thereby closing the circuit to the punch magnet 112 which througln intermediate mechanism is adapted to rock the depressor plate104 to actuate the selected punch 100. Subsequently the circuit of the magnet 112 will be broken allowing the return of the de pressed interposer to normal position.

Upon energization of punch magnet 112 in this manner its armature 113 (see also Fig. 2)

will be swung about its pivot and through link 114 will rock "a bell crank 115 to draw downward the link 116 and rock plate 104. Depression of any interposer 102 will, through incidental depression of bail 117, rock rod 97 to renderthe escapement mechanism effective and the rack 14 and the card carriage will advance one tooth to permit punching in the next column of the card.

Across the lower edge of all the interposers is a pivoted bail 118 reaching into notches in the interposers. depending finger 119 held against a bracket 120 on link 114 by a suitable spring 121. This spring also tends to pull link 119 downward- 1y rocking bail 1,18 clockwise into engagement with the right hand shoulders of the notches in the interposers. Link 119 has a shoulder near its free end normally hooked under the lower blade of contact 111. When an interposer 102 is advanced to operative position the bail 118 is rocked counterclockwise, raising link 119 and causing contacts 111 to be closed. As the punch passes through the card and link 114 moves to the right the bracket 120 will push the link 119 to the right so that the lower contact leaf will be released and contacts 111 will then open. llt will be recognizedfthat when the lower contact leaf is released contacts 111 cannot be closed again until the magnet 107 which effected their closing has been deenergized and the next punching operation effected.

Upcration of any punch may also be effected by manual depression of an key 109 corresponding to such punch. 1% contact 116a located atthe lower extremity of link 116 is adapted to be closed by the link upon each operation of the same.

Operation of the duplicator The operation of the punches 100 may also be controlled by means of the duplicator which causes the selector magnets 107 to be actuated in accordance with the perforations of a previously punched master card. Each of the magnets 107 is electrically connected to a related spring contact plate 122 4) a series of which is carried by an insulating block. Each spring 122 isadapted for a sliding continuous electrical contact with an associated brush 123 which is adapted to bear against a metal cylinder 124. The brushes Attached to the bail is a 123 are mounted in a -manner similar to brushes 71 (Fig. 10) and are similarly moved upwardly into cooperation with roller 124 Whenever magnet 125 is energized. A contact 126 is adapted to be opened by armature 127 when the latter is attracted by the magnet.

The master card is placed in position be tween arms 128 (see also Fig. 1) attached to and extending from escapement rack 14 so that the master card will advance step by step with the new cardbeing prepared. Closure of a door 129 causes closure of a pair of contacts 1.30 and a spring pressed latch 131 will hold the door shut. For further details of the construction and operation of the duplicator reference may be had to the application of F. L. Lee, Serial No. 307,819, filed September 24, 1928.

Uolwnn cat-out ha?" contacts The machine has provision in the form of a notched bar for cutting out reproducing operations. A contact controlled by this bar permits reproducing only when it is closed.

The bar 132 (Figs. 1, 5 and 12) is removably mounted on the bed-of the master card frame and has cut out portions 133a co-extensive with the columns or fields to be reproduced by the card in the sensing machine. Cam

portions 133 function to cut off the current to the sensing brushes 71 while the new card is in position to receive punching under control of the master card or manual keys 109. A. spring-pressed lever 128a is pivoted upon one arm 128 attached to escapement rack 14 and has a depending projection 134 moving with the rack between bar 132 and a universal rod 135 pivoted at 136. As the rack escapes, the cam portions 133 will urge projection 134 against bail 135 rockingit so thata depending finger 137 will coperate with a "pair of contacts, opening contact 138 and closing contact 139.

Skip bar The punching machine is provided with the usual skip bar 140 (Figs. 3, 6, 11-and 13) removably mounted upon escapement rack 14 and provided with suitable notches and cam surfaces which cooperate with the usual skip lifter arm 141 which has a beveled end 142.

-In a' well known manner depression of the 4 dog 94 will interrupt further movement of the rack beyond such point. The function of this skip bar 140 is to skip over the columns or fields which are not to be punched.

The sensing machine is provided with a similar skip bar 143 (Fig. 14) mounted on rack 14a. A lifter arm 144 (Fig. 11) cooperates with the bar to raise the stepping dog 91 of the sensing machine escapement. Arm 144 is mounted for vertical movement of its left end, and is arranged to be raised.

directly by the cam surfaces of the bar to elevate the stepping dog 91 and to permit engagement of the dog with rack 14a only when the arm cooperates with a notch. The function of this bar 143 is to skip overall columns or fields on a card which it is not desired to duplicate.

Miscellaneous contacts In Fig. 6, punching machine rack 14 carries a plate 145 adapted to engage and rock a lever 146 pivotedupon a fixed member of the machine when the last column of the card is in punching position. This lever, when so rocked will open contacts 147 and close contacts 148, 149and 150 (Fig. 7). The sensing machine has a similar set of contacts identified in the circuit diagram as 147a, 148a, and

lating material which when the new card is in position to receive punching in the first column, will abut and closes a pair of contacts 155. x The space key 109a (Fig. 2) is adapted to eifect an operation of the escapement'mechanism to advance the card one step in a known manner. In addition a pin 156 in the shank of the key will close a pair of contacts 157.

Release keys 158 and 15801 are also pro? vided in the punching and sensing machines respectively which in known manner effect 'mechanical release of their card carriage escapements to permit rapid advance to last column position.

Operation of the machine The operation will now be explained in connection with a specific example to bring out the various steps involved in the automatic reproduction of a group of cards;

A new card hereinafter called the e01 umn card is to be perforated under control of a previously punched card identified as the 45 column card. Other data will also be punched in the 80 column card from an 80, column master card. In Fig. 15 is shown a 45 column card certain of the data on which are to be reproduced in 80 column form as in Fig. 16. Examination of these two cards will show that the month, date, year, agency, serial No., sellingprice, consigned value, and stock are reproduced in fields of the same capacity that is fields employing the same number of columns as in the 45 column card. The code No. field has a greater capacity and this data is derived from the master card as is also-the data in the order number field and the X perforation in credit field.

To obtain the desired spacing, skip bar of Fig. 14 is cut to prevent reading of the columns of the 45 column card corresponding to the camming sections of the skip bar. Thus columns 1-10, 20-23, and 46-44, inclusive, are to be skipped and not read by the quently no punching will take place in these columns.

Cut out bar 132 (Fig. 12) is notched in this case to agree with the skip bar 140 to open the circuits to the duplicating brushes 123 in those fields which have perforations not to be duplicated from the master card.

The master card is an 80 column card arranged with perforations in the code No, credit and order No. fields which perforations are to be duplicated in each new 80 column card.

In operation, after 45 column cards to be reproduced, and new blank 80 column cards have been inserted in their respective card hoppers and the 80 column master card placed in its carriage, the machine is started by depressing the space key. Each ejector device then operates ('inefiectively since no cards are in ejecting position) and the automatic feeding device of each unit functions to bring one card into reading position and the other into punching position where their first columns are respectively beneath the sensing brushes and punches. At this point a contact closes which energizes the X key magnet of the punching machine causing the X or skip perforation in column No. 1 of the card. This causes the skip lifter to be operated and raised on the 80 column skip bar which causes the card to immediately space to the column in which reproduction punching is to commerce, namely column 36. The 45 column skip bar also causes its card to skip to the column at which automatic reading is to begin namely column 11.

As contact is established through a hole in column 11 of the 45 column card an impulse is transmitted to the punch selecting magnet corresponding to the index point position of the hole sensed and a hole is punched in the same index point position in column 36 of the new card. Concurrently, the escapement magnets of the two machines are energized and their respective escapement racks advance to present the next columns of the cards, namely the 12th and 37th columns.

This operation continues until the fields month, day, year, a.nd agency have been similarly reproduced. As the 45 column card escapes from column 19 to column 20 a rise on the 45 column skip bar causes the rack of this machine to move four columns to the left and no reading is taken from columns 20, 21, 22 or 23 since no current is supplied to the sensing brushes at this time. At this point reproducing stops.

As the 45 column card escapes from column 19 to 20 the 80 column card escapes from column 44 to 45 and a cam portion 183 in the cut out bar (Fig. 12) causes current to be supplied to the duplicating brushes 123 to sense the 45 column of the master card and data is punched in the code No. field. During the duplicating operations the escapement magnet of the sensing machine is not energized and the 45 column card remains at rest with its 24th column in line With its brushes.

As the column and master cards escape from the 53rd to the 54th columns a notch on the cut out bar switches the current from the duplicating brushes to the reproducing brushes and serial N 0., \selling price and consigned value are reproduced column by column. At this point switching is again effected by the cut out bar and a hole is punched in the X position in the first col umn of the credit field under control of the master card. The associated skip bar then advances the 80 column card to column 75 and the order No. field is subsequently punched under control of the master card.

During this operation, the 45 column card has been advanced by its skip bar to its column 45 Where it rests, awaiting the completion of the duplicating operations, when current is again switched to the sensing machine and the stock field is punched.

After this last column punching, if the machine is set for automatic ejecting each card will be ejected into its respective hopper and a pair of new cards fed into operating position and the foregoing sensing and punching operations repeate Circuit diagram In Fig. 17 is shown the wiring diagram of the electric circuit of the device. The wiring of the sensing machine is shown on the upper part of the sheet and the wiring of the punching machine is on the lower portion, the two sections being separated by the parallel broken lines. The connections between the two machines are indicated as individual broken lines which are collected within a single cable with suitable plug terminals for ready connection or disconnection.

The mechanical operations as outlined above will now be traced in the same sequence on the diagram. Current is supplied from a source through a switch 160 to lines 161 and 162. Assuming cards in position in the feed magazines, depression of space key 109a will establish a circuit as followszfrom line 161, wire 163, contact 148a, wire 164, contact 149, relay coil 165, resistance 166', space key con tact 157, to post 167 and back to line 162. Since it is assumed both carriages are in last column position at this time contacts 148a and 149 are closed. Energization of relay coil 165 closes its points 168 and the above circuit through coil 165 continues through points 168, ejector magnet 62, wire 169 to post 167 and line 162. Branching to wire 170, magnet 62a, wires 171 and 172, a parallel circuit also leads to post 167 and line 162, through contact 126, thus energizing both eject magnets 62 and 62a. This operates the -contact 126 to post 167 and line 162.

, Energization of magnets 70 and 7 0a trips their respective clutch dogs into engagement with their driving ratchets and also shifts contacts 45, 46 and 46a to supply current to the motors 20, a. Motor 20 is energized from line 161, wire 174, contact 46 (now closed) motor 20, contact 126 to post 167 and line 162. Motor 20a is energized from line 161, contact 46a (now closed) motor 20a, coil 173, wire 172, contact 126 to l'ne 162. Both motors thereupon advance a card to present its first .column to the sensing brushes or punches.

At the end of the feeding stroke, contacts 45, 46, 460 are unlatched and resume positions as shown.

A circuit may now be traced as follows: line 161, wire 174,'contact 45, wire 175, contact 147, wire 176, magnet 81, contact 147a, relay points 17 3a, wire 177, contact 138, wire 178, post 167, to line 162. Points 173a are normally closed and opened by their coil 173 during card feeding operations to prevent energization of the brush magnet 81 while the feed mechanism is in operation.

The above circuit energizes magnet 81 to raise the sensing brushes into contact with the card and conductor 72. At the same time contact 155 is closed completing a circuit to the 11 or X index point position selector magnet which punches an X hole in column 1 of the 80 column card and causes the skip lifter to-cooperate with the skip bar to escape this card to column 36. The selection circuit follows from line, 162, post 167, wire 178, wire 179, contact 155, wire 180 to wire 181 corresponding to 11 thence to magnet 107 of 11 position, wire 182, contact 152, wire 17 5, contact 45, Wire174 to line 16.1. Contact 111 is thereupon mechanically closed and punch magnet 112 is energized from line 161, contact 111, magnet 112, wire-183, wire 178 to post 167. A second circuit follows from line 161, contact 111, Wire 185, magnet 84, contact 82, wire 17 8, to post 167 In this manner the escape magnet 84 of the sensing unit is energized with the punch magnet 112. Magnet 84 is adjusted to operate faster than magnet 112 and the circuit to both magnets is broken as the Contact 111 opens. Suitable condensers are provided to cut down the arcing condition at this contact.

The construction of the skip bar of thesensing machine prevents the stepping dog entering the escapement rack and the rack 'as described until cards will consequently escape immediately upon completion of a feeding operation to present column 11 to the sensing brushes. As soon as contact 152 closes agam, the columns in fields headed month, day, year, and

agency are reproduced in rapid succession. Each selecting clrcuit-wlll follow from line 162, post 167', wire 17 8, contact 138, wire 177 contact 173a,, contact 153 to common conductor 72, hole in the card, brush 71, appropriate wire 184 to the corresponding magnet 107 2nd back to line'through contact 152 as beore.

As the column card advances from column 19 to 20 its skip bar escapes it to column 24. As the column card advances from column 44 to 45 its cut-out bar opens contact 138 and closes contact 139 thereby disconnecting the current supply to the reproducing brushesand connecting duplicating brushes 123 so that the successive columns in the code No. field will be punched under control of the master card. Each separate circuit follows from line 162, post 167 wire 17 8, contact 139, contact 130, conductor 124, hole in the card, brush 123, corresponding magnet 107 and back to line as before. Advancing from column 53 to 54, contacts 138, 139 are shifted back again and punching in fields serial No, selling price, and consigned value takes place under control of the 45 column card as before. Magnet 125 is energized toelevate brushes 123 into reading position by a circuit from line 161, wire 174, contact 45, wire 175, contact 147 magnet 125, contacts 130, 137, wire 178, back to line. After the last column of consigned value has been reproduced the 45 column card es capes to its 45th column and rests there while due to shifting of contacts 138, 139, credit and order N o. are punched under control of the master card in known manner. Re-

turn of contacts 138, 139 to the position of the diagram will cause. reproduction of the last column, namely stock.

As the punching machine escapes from the 79th to 80th column contacts 147. 148. 149 and 150 are shifted from the position of the diagram. Subsequent energization of magnet 112 holds contact 152 open.

- As the punch magnet is energized to punch in the 80th column, contact 116a is closed momentarily, setting up relay 165 through a shunt circuit around space key 157 to establish the starting circuit traced above. Contact 126 in series with magnet 37 and motor 20 prevents operation of these devices when the brushes 123 are against the card thus eliminating undue friction on the card while it is being fed into operating position.

Operation of the machine may be continued are exhausted. If desired, card levers and contacts may be provided to cut off automatic operation upon iii) failure of either card feeding mechanism to advance a card.

M punching Switches Switch 190 when open causes the machine to come to rest after each card reproducing cycle of operations. It is then necessary to depress the space key to resume.

Switch 191 when open permits data punching in the first column of the card by suppressing operation ofthe skip mechanism.

Switch 192 when closed will initiate a card feeding operation immediately upon closure of contacts 149 and 148a; Without Waiting for a punching operation in the 80th column.

The punching machine may be operated as a separate unit independently of the sensing machine by opening switches 193 and 194. To do this the sensing machine escapement rack must be to the extreme left holding contact 148a closed.

Closure of switch 195 will short circuit contact 139 and with contact 130 closed duplicating will take place automatically under control of the master card. Closure of switch 196 at this time will energize brush magnet 125 when the last column is being sensed to keep the brush 123 against the card this circuit follows from line 161, wire 174, contact 45, contact 152, switch 196, contact 150 (closed as the card advances from column 79 to 80), magnet 125, contact 130, switch 195, wire 178, post 167, to line 162.
